PETROLEUM-BURN ER.

SPECIFICATION formingpart of Letters Patent No. 418,243, dated December 31, 1889. Application filed March 13, 1889. Serial No. 303,124.. (No model.)

T0 all whom, it may concern:

Be it known that I, FEEDRICK H. SMITH, of Kansas City, Jackson county, Missouri, have invented certain new and useful Improvements in Petroleum-Burners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

This invention relates to certain improvements in burners, more especially petroleumburners, having for its object to promote com- .l

bustion, and therefore intensify the heat of the llame, thus augmenting the heat-ing capacity of the burner; and to these ends the nature of the invention consists of the detailed construction and combination of parts, as Will more fully appear from the following description and accompanying illustrations, in which- Figure l is a perspective View of my improved burner. Fig. 2 is a sectional elevation of the same. Fig. 3 is a detached perspective view of the initial burner, and Fig. l is a similar inverted view of the flamespreader.

In the embodiment of my invention I elnploy a retort A B, in its general outline circular and connected with a suitable tank or reservoir (not shown) containing the petroleum by means of a pipe a. The retort A B is cast with a central passage or tube F eX- tending vertically through it, While its bottom is cast with a downward central eXtension forming around said tube or passage an annular chamber G. The retort A B has a concaved or dished top or upper surface f, and setting or resting in its concavity, directly over or in alignment with the central passage or tube F, is a correspondingly-shaped plate or spreader E. This construction conforms more nearly to the form the flame takes as it leaves the flame-tube F, the concave surface f of the retort acting as a reflector to concentrate the heat and reflect it upward in a hollow or cylindrical body around the spreader or deflector. The spreader-Eis cast with a number of equidistant downward-extending projections or legs c c, which are tapered to points which rest in an annular groove coin the upper surface or top of the retort A B around the upper end of the llame-tube, thereby holding the spreader in position.

C is the initial burner, consisting of a pan supplied with a suitable absorbent-aa for instance, mineral wool. In the center of the bottom of the pan or burner C is a vertical stud h, having a screw-threaded upper end. Upon thepan or burner C rests a circular diaphragm of wire-cloth I, the same being incased in a circular frame or spider i, the radial arms or bars of which unite with a central-apertured hub-like portion, which lits upon the st ud h of the pan or burner C. This diaphragm confines and holds the absorbent in a compact condition in the initial burner, and also retains the heat in the latter sufficiently to cause the combustion to be more complete than if the absorbent Were exposed to drafts. Said diaphragm also serves to spread the liquid fuel as it flows into the initial burner, thereby distributing it evenly through the absorbent.

D is the burner proper, screwed upon the stud h, and having a iiame or jet tube g arranged immediately below and in alignment with the tube or passage F of the retortA B. The burnerD is connected with the retort A B by means of 'a pipe o, through which it is supplied with oil or petroleum. It will be observed that the retort being supplied With oil or petroleum, it (the latter) will enter the annular chamber G, filling that, and will pass into and flow through the pipe Z2, entering and filling it. The oil or petroleum overflowing the burner D will pass into the pan C, saturating the absorbent or mineral Wool therein. The oil or petroleum in the pan C is now ignited, the flame ascending and heating the burner D and its contained oil or petroleum, converting the latter into vapor or gas after having been a certain length of time subjected to the heat of the initial burner C. The gas or vapor of the burner D is now ignited at the jet-tube g, the flame from which ascends the tube or passage F, issuing from under and around the spreader. The fuel which flows over the fiat portion g is necessarily spread out and is very shallow, thereby facilitating its conversion into vapor, and the peculiar arrangement of the annular chamber G presents a large heatingsurface, which is exposed to the flame and heat of the burner. derstood that the burner in use is placed in Of course it will be un- IDO the fire-pot or combustioirchamber of va stove or other medium, thus taking the place of the fuel otherwise employed as the heating agent.

In order to clean the burner D, it is only necessary to detach itvfrom the stud 7L, when the sediment will flow out or ycan be readily cleaned out.

I am aware that it is old to provide a'down- Wardly-eonvexed deflector or spreader arranged over the ame-tube, and therefore l do not desire to claim this broadly; but I am not aware that burners have heretofore been constructed in the pecul iar shape herein shown and described-namely, with a concaved upper surface, Within which and over its central flame-tube is arranged a spreader or deector having lthe said convex shape. The deilector, as will be observed, is entirely received in the concavity of the retort and is beloW'the upper edge thereof, so as not to interfere with articles Which may be placed on the retort. The peculiar construction of the initial burner, with its gauze or Wire-cloth diaphragm, and the novel manner of connectng the burner D to said initial burner, whereby it is arranged overthe center of the latter and may be removed to enable it to be cleaned, will also be noted.

Having thus described my invention, WhatI claim as new, and desire to secure by Letters Patent, is-

In a petroleum-burner, the combination of the retort provided with a concaved upper surface and a central flame-tube, the downwardlyconvexed delector or spreader arranged over the flame-tube Within the said concavity of the retort and below the plane of the upper edge of the latter, and the burner arranged concentric with and below the lower end of the'fla1ne-tube, substantially as specified.

In testimony whereof l aflix my signature in presence of ytvvo witnesses.
